Data Centers Atlas: Iowa

News report: MCNI Concord Township Data Center

KIOW reported a county supervisor's account that a landowner was withdrawing from a proposed MCNI data-center land deal. Its earlier report described public opposition and an appealable agricultural-to-industrial rezoning denial. These are the outlet's accounts, not independently inspected land, zoning or appeal records, formal project withdrawal or a final environmental determination.

Record status: unknown. The later formal application or appeal disposition is unknown in this bounded review. A reported landowner decision about a business deal is distinct from a verified project withdrawal, final agency appeal outcome or resolution of every land-use objection.

Event date: Not established

Source publication date: October 17, 2026

Disposition date: Not established

Concern sources checked: October 18, 2026

The newer report does not establish an exact executed withdrawal, filing or agency event day. The earlier relative Wednesday vote description is not converted to an unverified exact date. The original current report JSON-LD records October 17, 2026 publication and a later same-day modification. The earlier report is dated September 10, 2026. Neither substitutes for an unverified formal filing day.

Raised or recorded by KIOW.

Counts describe attributed documentation, not harm or severity. Allegations, procedural outcomes and published replies retain their separate scope.

News report: Simple Mining Cedar Falls (rezoning defeated)

Iowa Public Radio reported residents' concerns about noise, water and electricity use, nearby habitat and property values around Simple Mining's proposed Cedar Falls location. The article distinguishes that proposal from the utility's Viking power plant. Its announced later discussion is not proof of a final rezoning outcome, measured effects or present mine operation.

Record status: unknown. The later disposition of the documented concerns and proposed rezoning is unknown in this bounded original-article review. An inherited title or a scheduled later discussion does not establish a final vote, current operation, measured noise or resolution of each concern.

Event date: Not established

Source publication date: March 26, 2026

Disposition date: Not established

Concern sources checked: October 18, 2026

The article reports an earlier rezoning discussion but does not establish its exact day in the bounded source. The event date stays unknown; planned April dates are not accomplished events. The original report displays March 26, 2026 publication, separate from the unknown exact discussion date and this source check.

Company statement reported by an outlet

Simple Mining stated, according to Iowa Public Radio, that it had worked with the city on larger, slower fans intended to reduce noise and offered tours. This is the outlet's account of the company position, not an independently inspected design, measured sound level or verified mitigation outcome.

The original article explicitly attributes this noise-design statement to Simple Mining in the same proposed-site discussion. March 26 is the outlet publication day, not an independently verified company-original date. Utility statements about closed-loop water and no wells belong to the separate power plant and are not assigned to this mine.

News report: Google Palo Data Center Campus

Iowa Public Radio reported residents' questions about water, electricity, traffic, lighting and noise at a town hall concerning Google's Palo proposal. The report describes differing county and mayor positions on local review and annexation. Those positions do not establish corporate motives, the applicable final rules, completed annexation, a permit outcome or measured impacts.

Record status: unknown. The later outcome of these documented questions is unknown in this bounded review. Mayor or county statements and requests for further detail do not resolve actual resource impacts, legal jurisdiction, permit conditions or current project status.

Event date: Not established

Source publication date: March 25, 2026

Disposition date: Not established

Concern sources checked: October 18, 2026

The March report describes a Tuesday town hall without an independently checked exact meeting day. The event date remains unknown; the publication day is not substituted. The original town-hall report displays March 25, 2026, with separate March 4 background reporting. Article updates and source checks do not establish a meeting or permit date.
